This invention relates toy a` tile breaker whereby tile may be accurately broken to any desired length.

An object of my invention is to provide novel means whereby the tile can be held and broken at any desired point.

A further object is to provide a tile breaker including a. movable breaking plate Which engages the under side of the tile at thefpoint at Which the tile is tobe broken.

Still another object is to provide a tool of the character stated which is simple in construction and effective in use.

Other objects, advantages, and features of invention may appear from'the accompanying drawings, the subjoined detailed description, and th-e appended claims.

In the draWingsf Figure 1 is a bottom plan view of my-tile breaker. .p

Figure 2 is a top` plan view of a reduced scale.

Figure 3 is a side elevation.

Figure 4 is a longitudinal, sectional View of my tile breaker, the handle and breaker plate being in elevation.v

Referring more particularly to the. draivings, my tool comprises a rectangular topt plate 1 from which sides 2 -2 depend. The top 1 and sides 2 are preferably integral. An L-shaped end Wall 3 is provided, the lower horizontal lip of said Wall having a plurality of bolt holes therein so that the tool can be mounted upon a bo-ard or the like if desired.

A U-shaped plate t extends across the top of the tool adjacent the center thereof, andthis plate is provided with a slot 5 which extends transversely of thev breaker. `The plate 1lis adjustable vertically so that the top thereof can be spaced any desired amount from the top 1. This adjustment is accomplished b-y means of screws G-6 which extend through the sides of the plate 4- and into the side Walls 2. A plurality of holes is provided in the plate 4 so that the desired adjustment can be made.

A breaker strip 8 extends transversely of the tool and is positioned under the top Wall 1. The top of the breaker strip is preferably sharpened and a transverse slot 9 is provided in thek top -Wall 1 through Which the breaker strip.' is adapted to extend. The slot 9 is directly under'the slot 5 in the plate a. v'ihe breaker strip 8 is reciprocated by means of Va handle 10. The handle is pivotally mounted on a rod 11, which rod is secured in the side Walls 2 2. The handle 10 is pivotally se' curedto the bottom of the breaker strip 8 pins 12e-12. Thus it'iviil be seen that when the outer end `of the handle l10 ispushed doWnWardl' the' breaker .strip 8' will be moved upwardly te engage the bottom ofthe tile and cause said tile to break .at that point.

A fibrousor hard rubber strip 18 issecured tothe bottom of the plate so as to protect the tile and prevent the upper glazed surface from becoming marred. The' breaker strip 8 is returned to its lov/ered position by means of a, leaf spring 14, one end of said leaf spring engaging a lug 15 on the breaker strip andthe other end of said spring extends through a slot ,16 in the, end Wall 3. The spring 14 is flexed downwardly bya block 17 on therunder surface of the top Wallv l. y i Y A rule 18 is mounted along one edge of the top plate 1,and this rule is also Visible through a slot 19 in the plate e. rihe purpose of the rule is to measure the amount which is to be cut off of thetile. A pair of guidestrips 20-20 is secured to the depending` si lcs 2 2 for vrthe purpose of guiding the `vertical yadjustment of the plate il. The depending endsy of the plate l fit between the guides wherebyl said plate is accurately held and guided as it is adjusted; i

The purpose of the slot k5 is to permit a sharp tool or glass cutter to be placed against the tile Which is positioned under the plato Ll. The. purpose of the glass cutter or tccl is to score the tileand thus cause it to break on va straight line. The tile is held firmly under the plate 1,the amount to be cut determined and measured on the rule 18, the glass cutter is then drawn across the tile, then/the handle 10`is depressed and the tile is broken by the breaker'strip '8. The slot 5 has the further advantage of accurately guiding the scoring tool or glass cutter.

-The lowered-surface of the `plate 4. is preferably.y concave yas shownin Figure 4f. YThe reason being that the tile will more readily break on a line directly between the slots 5 9.

Having described my invention, I claim:

l. A tile breaker comprising a top plate and depending sides, a. holding plate mounted on said first named plate and spaced from the top thereof, said last named plate having a slot formed therein, said first named plate having a slot formed therein below the 'first named slot, a breaker strip, means mounting said breaker strip below the first named plate, said breaker strip being adapted to extend through the slot in the first named plate, means to reciprocate said breaker strip whereby said breaker strip is urged through the slot in the Erst named plate and against the tile.

2. A tile breaker comprising a top plate and depending sides, a holding plate mounted on said first named plate and spaced from the top thereof, said last named plate having a slot formed therein, said first named plate having a slot formed therein below the firstv named slot, a breaker strip, means mounting said breaker strip below the first named plate, said breaker strip being adapted to extend through the slot in the first named plate, means to reciprocate said breaker strip whereby said breaker strip is urged through the slot in the first named plate and against the tile, and yieldable means engaging the breaker strip whereby said breaker strip is urged into lowered position.

3. A tile breaker comprising a top plate and depending sides, a tile holding plate spaced above the top plate, means adjustably mounting said tile holding plate, said tile holding plate having a slot therein, said top plate having a slot therein below the first named slot, a breaker strip adapted to eX- tend lhrough the slot in the top plate, a handle attached to the breaker strip, means pivotally mounting the handle whereby said breaker strip is moved upwardly through the ;lot in the top pla e and' against the tile.

4. A tile breaker comprising a top plate and depending sides, a. tile holding plate spaced above the top plate, means adjustably mounting said tile holding plate, said tile holding plate having a slot therein, said top plate having a slot therein below the first named slot, a breaker strip adapted to extend through the slot in the top plate, a handle attached to he breaker strip, means pivotally mounting the handle whereby said breaker strip is moved upwardly through the slot in the top plate and against the tile, and a leaf spring engaging the breaker strip whereby the breaker strip is urged into lowered position.

5. A tile breaker comprising a top plate and depending sides thereon, a U-shaped tile holding plate, means adjustably securing the tile holding plate to the side walls, said tile holding plate having a slot therein, said topv position, said tile holding plate having a concave bottom surface against which the tile bears.

In testimony whereof, I affix my signature. y
